Misconceptions and Truths About Hair, Hair Loss, and Gray Hair

 

People of all ages, genders, and backgrounds are paying more attention to hair care, investing significant time and money to achieve thick, shiny hair. However, effective hair care begins with acquiring accurate information and knowledge about hair health.

The American health platform *Prevention.com* sheds light on common misconceptions regarding hair growth, hair loss, and gray hair based on expert advice.

"Washing your hair frequently causes more hair loss?"

Washing your hair frequently does not lead to more hair loss. According to Dr. Jeffrey Benabio, a dermatologist, hair goes through a growth phase, a resting phase, and a shedding phase. During these stages, about 10% of your hair naturally falls out. While washing your hair and reducing friction from shampoo or water may help preserve a small amount of hair, you cannot prevent hairs that are already due to shed. Regardless of how often you wash your hair, a certain amount of hair loss is natural and remains unchanged.

"Dandruff is caused by dry scalp?"

Dandruff is not just a result of dry scalp; it can be triggered by various factors, often related to inflammation. Common causes of dandruff include conditions like psoriasis, eczema, and allergic dermatitis. One of the most frequent culprits is seborrheic dermatitis, which causes inflammation of the scalp and an overgrowth of yeast, leading to dandruff. Additionally, stress, certain medications, and medical conditions like Parkinson’s disease can worsen dandruff.

To improve dandruff, using anti-dandruff shampoos available at pharmacies and washing your hair daily is recommended. When applying shampoo, make sure to lather it thoroughly and leave it on for about five minutes before rinsing. If dandruff persists despite self-care, consulting a dermatologist is advisable.

"Extreme stress or fear can turn your hair white overnight?"

While stress can lead to the onset of gray hair, it does not happen overnight. Sudden, intense stress (such as the death of a loved one, major surgery, or severe illness) can damage melanocytes, the cells responsible for producing hair pigment. This can lead to the appearance of gray hair, but the effect takes several months to become noticeable since melanocytes are located deep in the scalp.

Other factors like hypothyroidism, as well as deficiencies in vitamin B12 and copper, can also contribute to stress-induced graying.

"Dry and weak hair requires supplements?"

To maintain healthy, moisturized hair, it's important to avoid activities that damage hair. Excessive use of hairdryers, swimming without a cap, tying the hair tightly, and frequent dyeing can all cause physical damage. Additionally, rapid weight loss or being underweight can negatively impact hair health, so increasing your caloric intake might help.

Incorporating healthy fats and B vitamins into your diet—found in foods like salmon, leafy greens, eggs, beef, and legumes—can significantly improve hair condition.
